Get rekt, dude. This is what a doomed-from-the-start marriage looks like. The YouTube description provides further context about this disastrous event as well:

While the wedding ceremony was under way, the bride and groom noticed a surprise guest. The groom’s secret girlfriend invited herself to the wedding but her presence wasn’t the only shocker. It was actually her attire that turned heads. She actually arrived at the ceremony wearing a wedding dress identical to the one the bride wore. Needless to say, the wedding ceremony – which was supposed to be a romantic occasion – took an abrupt nosedive and a knockdown, drag-out fight ensued.
